Seeing this error on 2 sites, both recently upgraded to MODX 2.8.0 and controlerrorLog to 1.4.0-beta.
[2020-10-12 00:20:04] (ERROR @ /home/site/core/components/controlerrorlog/processors/mgr/get.class.php : 131) PHP warning: dirname() expects exactly 1 parameter, 2 given
Once above error is cleared, ControlErrorLog is shows a notification but no error message content.
On a third site, I have both MODX 2.8.0 and controlErrorLog 1.4.0-beta, but do not see above issues.
